Under a tree by the side of the road, a man is sitting with his eyes closed. When you pass by, he suddenly opens his eyes and looks you over. "You're going the wrong way, dear friends. This is the final caution." Then there is a soft "Whummp", and he disappears right in front of your very eyes. All that remains is a small, steaming heap of leaves he sat on and a lingering smell of brimstone.
